Fedotov А.S. ALKYLATION OF TOLUOL'S BY CYKLOHEXEN IN PRENCE OF SULPHATE GLYCERINE' S ETHER Have been made analysis of different factors influence on appearance and chemical composition of alkirises products of toluol by cyclohexen in presence of sulphate glicerines ether usedas catalyst. It was shown selectivity and the service feriod in the process of alkirises. Key words: toluol, cyclohexen, catalyst, cycloalkirises.
Fedotov А.S., Fedotova N.F. THE INFLUENCE OF DEMULSIFYING AGENTS ON DEHYDRATION OF WATER-OI EMULSIONS IN YUZHNO-SUBBOTINSKIY AND KOMMUNAROWSKIY FIELDS The report provides the results of research into the causes for formation of water-oi emulsions and methods for their demolition by demulsifying agents at oil treatment plants and booster pump plants. It shows the effectiveness of Din-4 demulsifying agent with the presence of corrosion inhibitor "Concor" and without it at the wells of Yuzhno-Subbotinskiy and Kommunarovskiy fields of Orenburg Oblast. Key words: demulsifying agent, corrosion inhibitor "Concor".

Fedotov A.S.Raguzina L.M. DETERMINATION OF BROMINE IONS AND IODINE IN STRATAL AND BORACIC WATER The opportunity of changes of sodium thiosulfate solution on mean "Belizna" of household chemical goods at standard method is researched with aim to unify the analysis of stratal water on content of bromide- and iodide-ions. According to this long (5-7 days) and toxic process of mixing of working solution of sodium thiosulfate is excluded. This method can be used directly on oil wells.
Fedotov A.S., Kalimeneva O.A., Fedotov V.A. POLLUTED SULPHUR PURIFICATION AND MELTDOWN AT ORENBURG GPP The article discloses principal scheme of equipment for meltdown and purification of polluted sulphur, formatted in degassing, storage, warehousing and loading of sulphur goods. The equipment makes possible to get sulphur goods, excluding environment pollution, decreasing its cost and to use wastages for getting sulphur concrete.
N.A. Goncharenko, A.S. Fedotov, A.V. Dubinin, K.J. Vorobieva ALKENYLATION OF PHENOL BY OLEFINES AND SPIRITS AT PRESENCE OF SULFURIC ETHER OF GLYCOL In the article the results of experimental researches on alkenation of phenols by unsaturated hydrocarbons are given both at the presence of the catalyst - sulfuric ether of glycol, and at its absence. The results of interpretation of the received products of synthesis are given by results of the spectrometer analysis, the mechanism of process of alkenylation of phenol by olefines is offered.
Kazhanova T.V., Gataullin P.P., Almetkina L.A., Fedotov A.S. REACTION 3,4-DIFLAURINANILINE WITH CHLOROACETYLCHLORIDE The interaction of 3,4-diflaurinaniline with chloroacetylchloride proceeds with formation of products of the subsequent transformation of N-chloroacetyl-3,4-diflaurinaniline and results in N,N-diflaurinephenyl-diketopiperozine, amide of glycolic acids and to a simple ether of the last.
A.S. Fyedotov , R.R. Zainutdinov RAPID METHOD OF BROMINE ION DETERMINATION IN STRATUM WATERS. Investigations were held on improving bromine determination by sodium hypochloride solution, which was replaced by whiteness solution, as it takes five - seven days to get sodium chloride ready. This method can be used even in field condition, that is directly at the bore-hole.
